9 Claims.

This invention relates to a ring clincher which is particularlyapplicable for ringing hogs, applying clamping wires or rings to fencesor other similar purposes wherever it is desired to clinch a wire ringinto place.

The principal object of the invention is to provide a portable andmanually operated clincher with a magazine for carrying a plurality ofunclinched rings from which the rings may be fed into clinching positionautomatically as used.

Another feature of the invention resides in the adjustability of themagazine to accommodate rings of varying size within certain limits.

Still a further feature of the invention resides 16 in the relativemovement between the clinching ends of the clincher and the magazinewhereby the magazine will be retracted relative thereto as the ring isclinched so as to be positioned out of the way during the clinchingaction.

20 The full nature of the invention will be more clearly understood bythe accompanying drawing and the following description and claims:

Fig. 1 is a plan view of the clincher showing the ,magazine containing aplurality of unclinched rings. Fig. 2 is a plan view of the reverse sideshowing the clincher. Fig. 3 is the same as Fig. 1 showing the device inclinching position. Fig. 4 is a section taken on the line 4-4 of Fig. 1.

In the drawing there is shown a portable hand 0 operated clincher of theusual type which is somewhat in the form of a pair of pliers havingoppositely disposed jaws 10 and 10a provided with outwardly extendingcorresponding handles 11 and ,lla, said jaws and handles cries-crossingand having a pivotal connection through the medium of a bolt 12 providedwith a head 13.

Slidably supported upon the clincher, there is a magazine 14 having sidewalls 15 with inwardly extending forward portions 16 to conform with thegeneral shape of the unclinched rings 17. Said walls are of a height toaccommodate a number of unclinched rings as illustrated in Fig. 4.

A rear wall 18 is provided with upwardly extending fingers 19 extendingto substantially the height of the side walls 16, said rear wall havingrearwardly extending supports 20 provided with longitudinal slots 21through which the adjusting screws 22 extend. Through the medium or 0the slots and adjusting screws, the rear wall is slidable backward andforward to adjust it to varying sizes of rings.

Extending transversely of the magazine between the side walls and so asto bear on top of the rings, there is a follower bar 23 mounted on thefree end of the spring arm 24 which is firmly anchored at its oppositeend by the screw 25. The follower bar, through the spring tension of thespring arm 24, continuously bears against the top unclinched ring.

The Jaws 10 and 10a are provided with a curved recess 26 for receivingthe lowermost unclinched ring when the device is in the position shownin Figs. 1 and 2. When it is moved to unclinching position, as shown inFig. 3, the side walls of the recesses 26 in which the unclinched ringis seated force the free ends of the ring together to clinch them.

For obtaining further adjustment of the clinching action, particularlyin respect to varying sized rings, the clincher is provided with 1on--gitudinal slots 27 and 28, through which the pin 5a extends forpermitting the opening and closing movement, one of said longitudinalslots having adjustable set screws 29 and 30 extending 15 into theopposite ends thereof for limiting the sliding movement of the pin 25aWithin the slots.

In operation, the magazine is filled with a plurality of unclinchedrings as illustrated in Fig. 4. When the clincher is open, as shown in60 Figs. 1 and 2, the spring tension exerted on the upper ring by thefollower bar 23 forces the lowermost ring into the position between thewalls of the recesses 26. When the clincher is moved to the positionshown in Fig. 3, the walls 86 compress the ring, bringing the free endstogether in clinched position. Upon opening the clincher, the clinchedring is released and the follower bar forces the next lowermostunclinched ring into position.

Thus, the rings are fed automatically from the magazine into clinchingposition as the clincher is opened. By means or" the set screws 22, therear wall 18 of the magazine may be adjusted back and forth toaccommodate various sized rings within limits, and the set screws 29 and30 may be adjusted to vary the throw or the opening and closing movementof the clincher to accommodate the clinching action to the various sizedrings.

As illustrated in Figs. 1 and 3, it will be noted that the position ofthe magazine in respect to the clinching ends of the clincher isretracted so that the magazine will be out of the Way of 105 theclinching action when the ring is being applied. This is permitted bythe sliding action of the bolt 12 in the elongated slot of the magazine14. It is very important that this relative movement take place,otherwise the magazine would to said bar and the other end to saidmagazine prising a pair of clinching jaws, a magazine bar and the otherend to said magazine for exinterfere with the object to which the ringis applied during the clinching action.

The invention claimed is:

1. A portable hand operated ring clincher comprising a pair of clinchingjaws, a magazine in fixed relative position mounted thereon forreceiving a plurality of unclinched rings and supporting them inposition to be fed into said clinching jaws, rigid side walls formed onsaid magazine, a slidably adjustable rear wall mounted thereon foraccommodating said magazine to rings of varying sizes, and means forautomatically feeding said rings into clinching position.

2.
